Abstract types and methods in Swift

Read Original

This Swift programming article discusses abstract types and methods, explaining how they provide a base implementation for shared functionality. It compares using abstract base classes (with fatalError guards) to the preferred Swift protocol-oriented approach with associated types, using a model-loading example to illustrate polymorphism, type safety, and flexibility.
